Management of the safety of the road work location is the responsibility of the road manager. In general, knowledge about Occupational Health and Safety (OSH) is very broad, but there are several OHS components that are considered important to be used as a benchmark for understanding OSH. These components are K3 Definition and Initiation, K3 Management System (SMK3), Personal Protective Equipment (PPE), K3 Facilities and Infrastructure, OHS Risk. Research on the influence of occupational safety and health knowledge on occupational health on construction worker behavior was carried out to determine the effect of K3 knowledge variables together on the behavior of construction workers. And to know the effect of K3 knowledge variables partially on the behavior of construction workers. From the results of the study it can be concluded that there is a relationship or a low level of correlation between K3 Knowledge and Workers' Behavior while the value of the Determination Coefficient (adjusted r square) is 0.033 which means only 3.3% of K3 Knowledge aspects that affect Construction Worker Behavior and the remaining 96.7% is influenced by other variables. Based on the results of the T-test calculation using the method of calculation of Multiple Linear Regression the value of t count <t table, there is no significant effect of K3 knowledge variables (Definition and Initiation, Management Systems, Personal Protective Equipment, Facilities and Infrastructure, Risk) jointly towards Construction Worker Behavior on the Toll Road Development Project. Keywords OSH Management System, Determination Coefficient, Risk, T-test 1. Introduction Safety at the location of construction work and road maintenance is a dangerous job. Although there is no official data on the number of accidents related to road works, it is believed that the number of accidents at the location of road works is quite high. Heavy accidents at the location of road works are often reported in newspapers. Two recent accidents occurred on the Puncak - West Java route. A traffic guide is hit by a truck and dies while on duty. In another accident in a bridge maintenance project, five people were hit by an overloaded vehicle. Various studies abroad show that the risk of accidents with heavy or fatal casualties is three times higher than when there is road work. Therefore, many countries impose tougher sanctions for traffic violators at the location of road works. In general, knowledge about Occupational Health and Safety (OSH) is very broad, but there are several OHS components that are considered important to be used as a benchmark for understanding OSH. These components are K3 Definition and Initiation, K3 Management System (SMK3), Personal Protective Equipment (PPE), K3 Facilities and Infrastructure, OHS Risk. Useful definitions and initiations for the initial description of OSH in a construction project that is closely related to general recognition such as definitions of terms, abbreviations of abbreviations, meanings and meanings of OSH symbols, involved organizational structures, internal and external parties related to functions implementation of K3, and so on. The SMK3 process uses the PDCA (Plan Do Check Action) approach, which starts from planning, implementing, checking, and remedial actions.
